Abstract
Description
- The present disclosure relates to electrical connector plug assemblies and more particularly to plug assemblies which are mateable to a device that requires evidence of being tampered with.
- There are numerous applications, particularly in the automotive industry, whereby a plug assembly is connected to an electronic control unit (ECU) which provides I/O connections between the electronics and a drive or control system/component. These connections provide for the controls of various vehicles or equipment, which could be automobiles, other similar devices such as construction equipment, or any industrial/commercial/consumer equipment that requires tamper restrictions where an ECU controls various dynamic situations on the application. For example, the ECU may control such values as maximum rpm or maximum torque, and the like. These data points and/or settings are established by the original equipment manufacturer (OEM) in order that the maximum safe working conditions for various components are not exceeded, preventing components from being stressed beyond their designed limitations.
- However, users attempt to push the limits of the working parameters or gain additional functions of the equipment and, in some cases, actually reprogram the working limits of the various components by gaining access to the electrical terminals or “unmating” the connector and being able to remove or re-program certain electrical terminals and/or terminal locations. In some cases, re-programing the computer to make more power may not damage the equipment, but instead damage a system or component that was not designed to handle the additional power or other demand placed on it. In order for the OEMs to know, for warranty purposes, whether a connector assembly and/or its associated ECU have been tampered with, it would be advantageous to provide a connector assembly which provides evidence of tampering. These and other objects have been accomplished as provided herein.
- The objects were accomplished by providing an electrical connector assembly for attachment to a mating device, comprising a plug housing assembly; an attachment mechanism for attaching the plug housing assembly to the mating device; a wire dress cover attached to the plug housing assembly, with an access opening communicating with the attachment mechanism; and a locking element, receivable in the access opening and covering the attachment mechanism, and being retainable to the plug connector.
- In an another embodiment an electrical connector assembly comprises a first housing; a second housing latched to the first housing, the second housing having latching arms with latching surfaces; a cover attached to the first and second housing, with an access opening accessing the latching arms; and a locking element, receivable in the access opening and retainable to the latching arms of the cover, retaining the cover and the second housing together.

As shown best inFIG. 10 ,arms 126 are diametrically opposed to each other such that aradial opening 144 is defined betweenopposed shoulders 128. Finally, latches 146 (FIG. 10 ) are provided on an inner surface ofwall 124 and cooperate with latches 110 (FIGS. 7 and 8 ) provided onplug housing 4. - Referring now to
FIGS. 12-14 , thelocking element 8 is shown which is generally defined by ahandle portion 150, ashank portion 152 and arotatable latching member 154; theshank portion 152 androtatable latching member 154 defining a key member. Thehandle portion 150 is integral with atop portion 156 which defines a stop surface at 158.Handle 150 also includes a through opening at 160 which extends through at least a portion of thehandle 150. Shankportion 152 includes detent members in the form offlats 166 and includesprotrusions 168. - With the above described components and elements, the assembly and use of the connector assembly will now be described. With respect first to
FIGS. 2 , 7, 8 and 15, a subassembly is provided by placing the O-ring 24 in channel 90 (FIG. 7 ), and by placing retention insert 18 andmat seal 16 within the inner space 94 (FIG. 8 ) defined in theplug housing 4.Seal cover 14 may now be snapped to plughousing 4 as shown inFIG. 15 andjack screw 12 together withwasher 22 and O-ring 20 may be positioned in opening 140 (FIG. 11 )intermediate arms 126. As mentioned above, this places the threaded portion ofjack screw 12 within the enlarged opening 102 (FIG. 7 ). This also seatswasher 22 onshoulder 142. At this point, a plurality of contacts terminated to insulated conductors may be positioned throughapertures 122 ofseal cover 14, throughmat seal 16, throughcontact retainer 18 and finally into apertures 86 (FIGS. 7 and 8 ). As is known in the art, retainingnut 26 may be positioned around thejack screw 12 which retains the jack screw longitudinally within the assembly of theFIG. 15 components, but allows free rotational movement of thejack screw 12. - It should be appreciated that
wire dress cover 6 may now be positioned over the assembly ofFIG. 15 with cooperatinglatches wire dress cover 6 to plughousing 4. As shown inFIG. 16 , with thewire dress cover 6 snapped in place to plughousing 4, access opening 50 communicates with thejack screw 12 and with thearms 126 which extend upwardly from theseal cover 14. Thus theFIG. 16 configuration may be connected to a mating device with the jack screw connecting the assembly to the mating device. With respect now toFIGS. 16 and 17 , lockingelement 8 is shown with therotational latching members 154 aligned withkeyway slots 54. It should be appreciated thatrotational latching members 154 may be slideably received into the keyway slots which positions theshank 152 within thecylindrical portion 52 of thewire dress cover 6. When the lockingelement 8 is inserted into thewire dress cover 6 as shown inFIG. 16 , therotational latching members 154 are received within the radial openings 144 (FIG. 11 ); and are intermediate each of thearms 126, withshank portion 152 covering the top of thejack screw 12. An axial detent is provided between protrusions 168 (FIG. 12 ) onshank 152 and between detents 68 (FIG. 5 ) onwire dress cover 6. This position is shown byFIG. 17 . - With respect now to
FIG. 18 , the lockingelement 8 may now be rotated clockwise to the position shown inFIG. 18 whereby therotational latching members 154 are rotationally received undershoulders 128 whereby locking element is fixed in place. It should also be appreciated that a tactile snapping detent feel is encountered during the rotation of lockingelement 8 due to the interaction between detents 68 (FIG. 5 ) and the flats 166 (FIG. 12 ). At this point, a serialized lock wire 10 (FIG. 1 ) may be positioned throughtab 70 and throughopening 160 of lockingmember 8 which locks the lockingmember 8 in a fixed rotational sense relative to thewire dress cover 6. This design provides evidence of tampering, as the lockingelement 8 orwire dress cover 6 needs to be removed to reach the jack screw, and thewire 10 needs to be removed to remove the locking element. If thewire dress cover 6 is forcibly removed from the plug housing or the connector is “unmated” by turning the jack screw without first un-locking the lockingmember 8, therotational latching members 154 or the wire attachment features will break and provide evidence of tampering. - It should be appreciated that numerous different configurations are conceivable using the teachings of the present application. For example, and with reference to
FIGS. 19 and 20 , another version of wire dress cover is shown at 206, having a wire dress shroud at 232 and an access opening at 250. Multiple other configurations are possible, without departing from the teachings herein. Although most of the teachings herein represent a rotating locking member, it should also be appreciated that a locking member that slides into locked position rather than rotating is not a departure from this invention.
